Diagnosing Switch Indicators

 

Table A-1 Troubleshooting Chart

Symptom

Action

Power LED is Off

• Power supply is disconnected.

 

• Check connections between the switch, the power cord, and the wall outlet.

 

• Contact your dealer for assistance.

 

 

Power LED is Amber

• Internal power supply has failed. Contact your local dealer for assistance.

 

 

Diag LED is Amber

• Power cycle the switch to try and clear the condition.

 

• If the condition does not clear, contact your dealer for assistance.

 

 

Link LED is Off

• Verify that the switch and attached device are powered on.

 

• Be sure the cable is plugged into both the switch and corresponding device.

 

• Verify that the proper cable type is used and its length does not exceed specified

 

limits.

 

• Check the adapter on the attached device and cable connections for possible

 

defects. Replace the defective adapter or cable if necessary.

 

 

Diagnosing Power Problems with the LEDs

The Power and RPS LEDs work in combination to indicate power status as follows.

 

 

Table A-2 Power/RPS LEDs

Power LED

RPS LED

Status

 

 

 

Green

Green

Internal power functioning normally; RPS is present.

 

 

 

Green

Amber

Internal power functioning normally; RPS plugged in but faulty.

 

 

 

Green

Off

Internal power functioning normally; RPS not plugged in.

 

 

 

Amber

Green

Internal power faulty; RPS delivering power.

 

 

 

Off

Off

Both internal power and RPS unplugged or not functioning.

 

 

 

Power and Cooling Problems

If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the unit are unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective.

ES3628EA specifications

Accton Technology's ES3628EA is an advanced network switch designed to meet the growing demands of modern enterprise environments. This managed switch is engineered to provide a robust solution for delivering high-speed connectivity and reliable performance across local area networks (LANs). The ES3628EA features a 28-port configuration, combining 24 Gigabit Ethernet ports and 4 SFP (Small Form-factor Pluggable) uplink slots, allowing for flexible network design and scalability.

One of the standout characteristics of the ES3628EA is its support for Layer 2 and Layer 3 functionalities, offering network administrators enhanced control and management over data traffic. With features such as VLAN (Virtual Local Area Network) support, the switch enables efficient segmentation of networks for improved security and performance. VLAN tagging allows for the separation of different data types on the same physical infrastructure, reducing broadcast traffic and enhancing overall efficiency.

Additionally, the ES3628EA supports advanced Quality of Service (QoS) mechanisms, which prioritize critical network traffic, ensuring optimal performance for applications like voice over IP (VoIP) and video streaming. The ability to configure multiple queues allows administrators to define traffic patterns, allocate bandwidth effectively, and minimize latency.

The device also incorporates comprehensive security features, including port security, access control lists (ACLs), and support for802.1x authentication. These capabilities help safeguard sensitive data and restrict unauthorized access to the network.

Power over Ethernet (PoE) support is another significant feature of the ES3628EA. This technology allows the switch to deliver power alongside data over Ethernet cables, facilitating the connection and powering of devices like IP cameras, VoIP phones, and wireless access points, all without the need for additional power sources.

Furthermore, the ES3628EA boasts a user-friendly web-based interface for configuration and management, making it accessible for network administrators of varying expertise. In addition to the web interface, it also supports SNMP (Simple Network Management Protocol) for more advanced network monitoring and control.

Designed for reliability and performance, the Accton Technology ES3628EA is a versatile solution that integrates seamlessly into diverse networking environments, delivering the capabilities required for today’s demanding applications. Its blend of speed, security, and advanced management functionalities makes it an excellent choice for enterprises looking to enhance their network infrastructure.
